User manual - FLOW METER SPI-638
7.3.8.
“ Init d
” parameter
This parameter defines type of the value displayed after power on the meter. It is possible
to set it to:
“Flo”
- current flow rate (instantaneous flow),
“bAt”
- batcher counter,
“tot”
- lowest part of total flow counter (less significant digits),
“tot2”
- medium part of total flow counter,
“tot3”
- highest part of total flow counter (most significant digits),
If value
“tot2”
or
“tot3”
is selected, meter automatically switches display to non-
zero part of total counter result. Flashing (or not, if result is shorter than 6 digits)
decimal points indicates which one part is actually displayed.
7.3.9.
“FiLtEr” menu
This menu contains parameters referred to additional data (result) filtration.
“vALUE”
- this parameter sets filtration rate. It can be set to values from 0
(no filtration ) to 5 (strongest filtration – time window about 3.5 sec.).
“droP”
- this parameter defines minimum percentage change of measured value which turns
off (temporally) data filtration. Value of this parameter can be changed in range:
0 ÷ 199,9%. Main purpose of this parameter is acceleration of displaying data
changes, when sudden changes of instantaneous measurements value occur (while
parameter
“vALUE”
is set to high values).
7.3.10.
”OutP” menu
This menu contains parameters of analogue output control. Menu is available if the
device is equipped witch analogue output.
Analogue output can be controlled depend on both present measured value and
peak value (if peak detection is enabled).
“OUtmod”
- analogue output mode. Depending on version of the device there are
following options:
For active current output:
”
oFF
”
- current output disabled
,
”
0-20
”
- current output enabled with 0 ÷ 20 mA mode
,
“
4-20
”
- current output enabled with 4 ÷ 20 mA mode,
”
modbuS
”
- current output controlled via RS-485 interface.
For passive current output:
”
oFF
”
- current output disabled
,
“
4-20
”
- current output enabled with 4 ÷ 20 mA mode,
”
modbuS
”
- current output controlled via RS-485 interface.
